"Blue Sky Bakery is a tiny cafe near the Barclays Center known for its muffins. They wholesale them to places around the city, but the shop is a popular stop for Park Slope people on their way to work in the morning. These muffins are unbelievably good, stuffed with fruits, and never too sugary or sweet. Get there early - they close at 2pm and the best muffins sell out by late morning." - Matt Tervooren
